Title: Endless rolling method of hot strip mill line
Inventor: HIRA TAKAAKI
IPC: B21B15/00
Filed: 1984-12-19
Abstract: PURPOSE:To perform the continuous finish rolling by surely pressure-welding preceding and succeeding steel strips to each other, by prewelding the rear end-face of preceding strip and the front end-face of succeeding one together, before rolling the strips under a limited draft. CONSTITUTION:After finishing the rough rolling of a preceding steel strip, its rear end-face is abutted to the front end-face of a succeeding strip; and after prewelding at least both ends in the width direction of the abutted part of both strips to each other, the welded parts are subjected to rolling reduction under a <=20% draft before supplying the strips to a finishing mill to roll them. At that time, the prewelding allowance is required to be >=0.1B, and the thickness of all scales is regulated to <=20mum, and the rolling under a <=20% draft is required.

Title: Discoid recording medium
Inventor: NAKAYAMA MASAYUKI
IPC: G11B21/08
Filed: 1986-11-11
Abstract: PURPOSE:To accurately execute a head positioning by providing special tracks for track number counting, and detecting the number of tracks that a head crosses. CONSTITUTION:On the recording surface of a recording medium DM that rotates in the direction of R, plural tracks are formed coaxially, and sector servo signal areas SS are formed in a manner that they divide said tracks at every determined angle resulting fan-shaped segments. And, the special tracks ST for head-crossing track number counting are coaxially formed at a rate one per plural tracks; other tracks are made tracks DT for data recording. At the time of high-speed shifting of a head, said special tracks ST are sequentially detected to obtain approximate number of pieces of tracks that the head crosses. At a time when the head approaches a targeted track and its moving speed decreases, a highly accurate tracking should be achieved based on the result of a servo signal reading. In such a way, the accessing by head can be executed accurately and at a high speed.

IPC: B64C27/82
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To increase thrust produced by a duct by forming a duct lip forming the suction port of the duct suction port in shape out of an ellipse of which the major axis is located in the outer diameter direction from the axial center of the duct. SOLUTION: A duct 1 is provided while being perpendicularly intersected with the body axis of a helicopter, fan blades 2 are provided for the outer circumferential periphery of a center body 3, and they are rotated within the duct 1, so that thrust is thereby developed. In addition, a duct lip 4 is formed into the suction port of the duct 1.

The larger surface area where there exists the axial constituent Psa of static pressure, is more subjected to greater thrust developed at the duct lip part 4. By this constitution, thrust greater than thrust which can be normally developed by the fan blades and fans, can thereby the developed.

Title: Tuner circuit
Inventor: TAKAHIRA TAMOTSU
IPC: H04N5/44
Filed: 1993-10-26
Abstract: PURPOSE:To prevent malfunction of a voltage controlled oscillator(VCO) due to local drift and to improve the operability of tuning by reducing the level of an audio IF signal when any synchronizing signal is not detected from a video detect signal. CONSTITUTION:When a local oscillation frequency drifts higher due to the change of a surrounding temperature or the like in the case of channel switching, the video and audio IF signals with transited higher frequencies are outputted from a front end 12. At such a time, when the synchronizing signal is not detected, the audio IF signal is attenuated, and the video IF signal and the level-suppressed audio IF signal are inputted to an IC 26. Therefore, the oscillated frequency of the VCO circuit is almost not affected by the audio IF, and the pull-in range of the VCO circuit is not made narrow. When the oscillated frequency of the VCO circuit is locked to the video IF, a detection signal containing a video component is outputted from a video detection circuit and with this signal, a switch 22 is turned off.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent defect of a floating source bias method from being generated and to automatically compensate for the fluctuation of a physical characteristic of an individual FET by biasing a field effect transistor by using a simple voltage source. SOLUTION: Voltage is generated on source resistance R5 to obtain desired drain current. Voltage applied to the resistance adjusts the resistance so that it may be larger than gate G to source S voltage that is necessary an FET which operates with desired current. Also, desired drain current decides voltage that is applied to a drain resistance R1 . This voltage is compared with reference voltage that is decided by CR1, R2 and R3 which accompany a bipolar transistor Q1 . Current that flows through the Q1 flows to that Vbe of an emitter may fall onto reference voltage (generally 0.65 volt). Current that flows through R4 generates gate bias voltage of the FET and further realizes stationary drain current.

Abstract: PURPOSE:To obtain a cable, whose insulated core is difficult to draw off from an external conductor, by making the size of air foam near the outer periphery of a foamable resin larger than the size of air foam at the central part thereof when the foamable resin is extruded, for coating, over the surface of a center conductor to provide a foamed insulated electric wire for coaxial cable. CONSTITUTION:Pellet-like raw material resin is charged into a barrel 2 from a hopper 4 and is heated therein up to a temperature higher than the melting point. Then, a gas of foaming agent is injected from a gas injection hole 5 while the resin is being stirred by a screw 14 and a projection 16, in which condition, the gas is diffused into the resin. Next, the resulting resin is introduced into a space 28 via an extruding port 6 and a molten-resin supply port 10 and then is coated, from a coating port 20, over the outer peripheral surface of a central conductor 18 sent out from a tip end portion of a feed pipe 22.
